This rim has a continiionsiupstanding ilnnge il provided v. ith un inclined upper l'aee 4. On the. opposite edge of the riin l'roin thc ilange 3 are provided a number i of downwardly projecting ears Oi flan es 5 for a modification of the general form of structure therein claimed. As stated in the above named cases, rims of this character comriee generally speaking, a rim fixed to the ell and a detachable rim capable of be.- ng easily removed from or attached to the fixed rim and provided with means foi readily engaging or dis'engaging a tire.

They side of the fixed rim E which carries the ears is provided with a face 7 inclined in the saine direction as face 4-. The tire. is carried by a detacliablerim 8.

More specifically this invention contemplates-the provision of a s 'tremovablerim combined n itli detachab e annular tire retaining flanges, the rim t the anges and of expansion to cause it to 1 "his rini is p and the whole carried from place to lace i W ien emitracted the. ilanges 10 which are ready to be immediately substituted. `or a l endless can be slipped over the riin ilanges 94 damaged tire whenever necessary. Means l and the tire can ie easily removed. In this illustration l have shown the detachable flanges 10 as shaped to hold a cleneher tire, but it is obvious that bv properly forinin them, any other forni oi tire may be use ln order to hold the ends of the split detachable rim in proper position when in o eifation, a key piove 1l is used which may e of the 'l'orin described and claimed in my appliare also provided in the shape. of a loekingring which may be retainer iiilplaee by a keeper for holdin" the two rims iii engagei ment. This modification contemplates a special form of keeper which may be slipped i to one side to disengage the ocking-ring without entirely removing the nut whit-hl holds the keeper in place. This siinilies y and facilitates the removal of the dotac iable cation, Serial No. 375,717, liled oi' even date rirn and maintains the elements of the fixed herewith. A key piece of this form has inrim and attached parts in semi-assembled i elined end faces 12 which engage with the condition. It is to be understood lionover similarlyr inclined ends of the detachable split that the invention is not limited to the spcrim. The key piece is also provided with roeific forms selected for purposes of ilhistrai jor-ting lugs I3 which take under the en s of tion, but that the dili'crent parte ina be l thesplitriiil. rlhekey iieceis provided with freely modified so long as their several unc an o iening to lit over the valve stein 14,' and tions are` erforined relatively to each other is held in place by a nut 15 on the valve Stern. withoutii. tering the elfective combination of 'lhe valve stein also carries a clip of usual elements. i form 16. On the lower surfaces of the de- 1n the tachablc riin are a pair of oppoiiitely` inclined 1 is a transverse faces 17 and 1S. The face 17 engages the` drawings Figure tire taken on the riin and Fig. 4 is a central lon similarly inclined face 4 on the fixed rim, but faces 18 and 7 being oppositely inclined, leave a V-shaped opening between them. In this opening is .fitted a locking-r'mg 19 which holds the two rims in )roper relation. This ring is held in position y keepers 2O of which there may be any desired number. These eepers 20 are each provided with an elongated slot 21 to fit over the studs 6 before referred to.

The operation of the I f th tachable rim are drawn together and lapped over each other if necessary, thus redlicin the diameter of the detachable rim sufiicientlyto ermit one of the flange rings 10 to be slippe The tire 1s then slipped over the detachable rim and fitted to ange ring is then put in place and the detacha` lellrim expanded until the flange rings and tir piece is the put in place and by screwing up he nut piece and clip 16 are rawn toliing the ends of the detachable The tire e tire and detachhe *key 15, e ke ge er loc ri in fixed expanded c n now be inflated and t a le rim bein firmly fixed together can be directly attached to the fixed rim and fell sha e groove between the faces 7 and 18 an the eepers brought into the locking ring. By the use of the s otted eeper, it will be seen it is only necessary to oosen the nuts 22 slightly when the keepers can be slipped inwardly until the bent e ges 23 lie below the ears 5 when the keepers will it closely engages tinside of l place a ainst be entirely free from the locking ring 19 and l it can be removed. Then when the locking ring is in place again, it is only necessar slice the ee ers up in en agement wit and ti hten t e nuts slight y. This saves a great (ical of screwing and unscrewing of the nuts and also makes it impossible to mislay or lose the nuts and keep A great saving of time in changing tires is thus effected, ay matter which is often of the very greatest importance as in races.

Having thus described my invention, I claim:

1. -In a vehicle wheel in combination, a felly, a fixed rim, a detachable rim, a lockement ocking to it ring in place.

means carried by the detachable aging a tire, a locking ring and slotted eepers for holding said lookin f ring in place. 3. In combinat1on in a vehicle wheel, a l fixed rim having an upstanding flan e at one l edge, the upper face of said flange eing inclined, a similarly inclined face at the other edge of said rim, a split detachable rim carrying tire-engaging means, said rim being provided with oppositely inclined faces, one of said faces engaging the inclined face on the upstanding flange, and lying opposite to the inclined face on the other edge of the fixed rim, a locking ring adapted to engage said last two faces, studs projecting from said fixed rim and radially slotted keepers mounted on said studs and enga ing the locking ring. 4. n combination in a vehicle wheel, a felly, a fixed rim attached to said telly and provided at one side thereof with downwardly projecting ears, studs carried by said ears an projectin laterally, a detachable rim adapted to elige over said locking ring for holding said in place,
